Original Abstract Submitted

In aspects of a Selective Retransmission Request (SeRQ) protocol proposed herein for wireless communication, a UE may group Retransmission Request (RTQ) feedback information bits for a plurality of transport blocks (TBs). The RTQ feedback information may be understood to indicate, to a non-terrestrial transmit receive point (NT-TRP), which TBs, among the plurality of TBs in the window, were not decoded properly. UEs may generate RTQ feedback information bits for a group of TBs received during a single window or TBs that have been received during multiple, distinct windows. The generation, by the UEs, of the RTQ feedback information bits for a group of TBs may be encoded based on, e.g., source coding, codebooks, binomial coefficients, etc. Upon receipt of a retransmitted version of a given TB, the UE may combine previously received bits of the given TB with the retransmitted TB version of the given TB.
